Susie Orman argues that you can have more money by saving $100 each month (starting at the end of this month for 12 deposits) instead of saving $1,200 at the end of each year. To check whether that is true, you are going to compare saving $600 every six months for a year (starting from 6 months from today for 2 deposits) vis-à-vis $1,200 at the end of the year.
What is the future value of $600 saved every six months for a year at the end of the first year at 10% APR?
